There are areas where over 40 species may grow in a hectare. Trees in the rainforest grow in layers. The layers are the Upper Layer (54 m high), the Middle Layer (15 m to 45 m) and the Under Layer (5 m to 15 m). The trees in the Upper Layer form a thick canopy with their leaves, which blocks 95% of the sunlight.
